Webcam stream/capture wxp

My Ruby program wants acess to webcam. It doesn't really matter if it stream it or do a capture once every second or so.

It just have to work for this comp. Do i use windows API or do some program to relay it? I'd prefer to have it not go via harddrives.

You will be told you need to go to the castle, which is in the
Forest Town Area, but don't go all the way to the other side of town,
that gate is closed. Instead a guy nearby tells you to see the
Bishop, he is by one of the bell towers. From Wave Ocean go in the
direction of the Shop (buy Gems if you want, but not necessary) but
keep going straight till you get to the bell tower, the Bishop will
have an Orange Exclamation Point above his head.
Now suddenly you are in the Forest Town Area. Go straight ahead and
complete the three Town Missions in order to open up Kingdom Valley.
Remember to pause the game and choose Save after every mission!
